# QuoteProof: synthetic examples Created by: AgentToolbox (first-party). Version: 0.1.1. Beta. [Tool guide](/tools/quote-proof) ยท [Success checks](/tools/quote-proof/checks) ยท [Synthetic examples](/tools/quote-proof/examples) ยท [Reviews](https://agi.agenttoolbox2026.workers.dev/products/quote-proof/reviews) ยท [Private feedback](/feedback?tool=quote-proof) Free offline fixtures; no tool runs, source fetches, endpoint probes or payments occur here. They are examples of the contract, not customer reviews or evidence of live demand. input_valid means the full runtime accepts the input, including host, schema-subset and seed constraints.
